If you want to delete files with spaces or names like "-t" then this simple method works well too. You might want to try {system( "rm -i -- \"" $0 "\"" )} if you worry about deleting the wrong files. These kinds of scripts are scary.

awk '{system( "rm -- \"" $0 "\" 2> /dev/null" )}' file

Cheers,

xargs rm < filename

where filename is the name of file containing the files to be deleted..
